ABSTRACT:
An extruder for extruding pasta in the form of a continuous thin strip in a pasta-making machine, more particularly for domestic use.
The extruder comprises a first tubular body and a coaxial inner jacket defining a circular opening of predetermined diameter "D". A second tubular body having a flange comprises a coaxial cylindrical body held in position by a number of rigid radial elements defining passages and is engaged coaxially in body. The outer diameter "d" of body is less than the diameter "D" and defines a slot for extruding pasta in the form of a continuous tube which is automatically cut along a generatrix by a tooth secured to the outer surface of body.
The components of extruder can be axially dismantled in order to remove residues of pasta after the extrusion process. Jacket also has projections which slow down the pasta as it travels in the passage, thus bringing it to the same speed as the pasta encountering the radial elements.
